A while loop executes instructions within a block as long as a specified condition is met. The while loops are created using the while keyword. It takes the following form:
while (condition) { … }
As in the case of the for loop, the block is optional in the case where only one sentence is within the scope of the loop. In a while loop, the statements in the block execute repeatedly while the condition specified still holds. Consider the following code:
val names = arrayOf("Jeffrey", "William", "Golding", "Segun", "Bob")var i = 0while (!names[i].equals("Segun")) { println("I am not Segun.") i++}
In the preceding program, the block of code within the while loop executes and prints I am not Segun until the name Segun is encountered. ...
